Description

General description

Calcium chloride (CaCl₂) is inexpensive, easily available calcium salt with a wide range of applications. It is a key component in deicers as it melts snow and ice. Reports suggest that CaCl₂ helps in retaining the firmness of fresh cut fruits and vegetables during the storage.

Application

Calcium chloride may be used in the following processes:

• Modification of natural zeolite to increase its ability of fluoride removal.
• Synthesis of calcium sulfate whiskers utilized in making polymer reinforcing composite materials.
• Synthesis of calcium chloride-anodized aluminum composites, a solid sorbent.
• As an extractant in the soil analysis process.
• As a catalyst in the synthesis of aldols by reacting dimethylsilyl (DMS) enolates with aldehydes.
